I wasn't a fan of it either... but if it kills a break I guess it puts the ref in a spot to have to make a decision... and if the ref remembers he already had a yellow on him he may have kept the card in his pocket

Sure, in a normal game I think that's a yellow. But with some of the fouls that have been not called and the competitiveness of the game, seemed out of place. I do agree that he didn't realize the guy had a yellow already, which just falls under shitty refereeing
